Session 8 - Humanitarian & Healthcare Logistics

Session 8 - Humanitarian & Healthcare Logistics #

Dr Jose Escribano

The COVID emergency has highlighted the dependency of society on international supply chains to maintain our current standard of living. This session expands upon what we have learned about the shortest path problem, facility location problem and vehicle routing problem to consider features such as multi-modal and multi-commodity supply chains.

We study these in the context of humanitarian supply chains, which aim to deliver as much material as possible within a specific frame instead of seeking to minimise costs. We will also discuss the application of the methods reviewed in this lecture in the context of healthcare logistics and the concept of push and pull supply chains.
